A Note on the Chernobyl Nuclear Disaster

The disaster had more of an effect on eastern Europe’s nuclear experimentation and use but “While no-one in the West was under any illusion about the safety of early Soviet reactor designs, some lessons learned have also been applicable to Western plants” (World Nuclear Association). Since the Chernobyl disaster was majorly caused by human error and under qualified scientists, to work with nuclear reactors today you need to be insanely qualified. Since the accident, Soviet-designed reactors’ safety has improved greatly, even in smaller ways. Automatic shutdown mechanisms now work faster, and other safety mechanisms have been sped up. Even new equipment has been installed such as automated inspection equipment. Several scientist and reporters have even said an accident like Chernobyl is virtually impossible with today’s technology (World Nuclear Association).

On Saturday, 26 April 1986 a reactor at the Chernobyl Power Plant near Pripyat, Russia has a sudden power surge which caused mass damage. The Power Plant tried for immediate

The Chernobyl reactor 4 exploded on 26 April 1986 in a steam turbine test, which was carried out to determine how long turbines would spin and supply power to the main circulating pumps following a loss of main electrical power supply. A gradual reduction of power output was needed in preparation for the test, but during the process the reactor went in an unintended shutdown state, with a power output much lower than the requirement. To recover the reactor’s power level, operators decided to withdraw control rods manually, leading to an extremely unstable reactor configuration. A series of following improper operations and the original designing flaws of the reactor eventually resulted in a steam explosion. The first explosion released fission products to the atmosphere and

There have been lots of nuclear accident around the world. One of the accident that had a major impact on the world was the Chernobyl disaster. The disaster took place on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The disaster was caused by a reaction explosion induced by design faults and staff application errors. The accident took place in the course of scheduled tests to check the power supply mode in the event of external sources loss. Even after 10 days, explosions and ejections of radioactive substances continued. The release of radiation and radioactive substance polluted the places within 30 km of Chernobyl, and those areas have been closed for a long period of

As a basis Chernobyl was a major nuclear plant accident, which took many lives with it. It was a situation in which it could have been easily avoided and many precious lives could have been saved. Due to lack of responsibility, ignorance abuse of power and selfishness this disaster was inevitable. Such an accident killed so many people and destroyed so many people’s lives with a single explosion. People still today receive the dreadful news that they now have cancer after so many years it still has a dreadful effect on them. Not only did this damage human life but the animals that are unfortunately still love there today and the beautiful environment and the plants that used to blossom once before. Not only was Chernobyl its self destroyed

On the afternoon of April 26th, the staffs of the Chernobyl nuclear plant were about to do testing on the fourth unit of the nuclear facility, and ultimately the unit that caused the destruction of the plant. They were testing safety features of certain hardware to see if the system could run for a minute in the catastrophic event of total power failure. (Leatherbarrow) The purpose of the pumps and steam turbine system that was being tested was to keep the reactor having cool water flow to the core continuously. Without a constant water flow to cool the core, the reactor itself would ultimately melt down.

n April 26 1986, one of the most destructive man made accident happened. Chernobyl, a Ukrainian city flourished with people and energy. Not just any kind of energy, but the most lethal energy source… Nuclear Energy. On this day, the most lethal energy turned rouge against Chernobyl. The city was never the same again.

Early in the morning of April 27, 1986, the world experienced its largest nuclear disaster ever (Gould 40). While violating safety protocol during a test, Reactor 4 at the Chernobyl power plant was placed in a severely unstable state, and in a matter of seconds the reactor output shot up to 120 times the rated output (Flavin 8). The resulting steam explosion tossed aside the reactor’s 1,000 ton concrete covering and released radioactive particles up to one and a half miles into the sky (Gould 38). The explosion and resulting fires caused 31 immediate deaths and over a thousand injuries, including radiation poisoning (Flavin 5). After the

The main reason for the mishap is by now well recognized (Petryna 1). However, initially the Chernobyl catastrophe baffled the minds of people in the 20th century and definitely left the people of Ukraine disordered while living in anxiety. Now, without question, the public knows that the accident at Chernobyl was the result of a disastrous combination of ignorance from the Ukrainians and complacency from the Soviets in control of Ukraine at the time. As according to American physicist and Nobel laureate Hans Bethe, “…the Chernobyl disaster tells us about the deficiencies of the Soviet political and administrative system rather than about problems with nuclear power." The immediate basis of the Chernobyl accident was a mismanaged electrical-engineering experiment (Rhodes "Chernobyl", PBS). While, the indirect source of the calamity was an industrial malfunction of a Soviet made nuclear-based machine. Ironically, the Chernobyl accident occurred during a test run, which was conducted to improve plant safety. This accident proved once more what experienced control engineers have all learned: that a process must be understood before it can be controlled. (Liptak “Control Global”). Engineers with no familiarity of reactor physics were interested to see if they could draw electricity from the turbine generator of the Number 4 reactor unit to run water pumps during an emergency, when the turbine was no longer being driven by the reactor but was

"After Chernobyl, thousands and thousands of people, if not millions, were given a death penalty and had to pay the price..." (Wladimir Klitschko). On April 26, 1986, the Chernobyl Power Station in Pripyat, Ukraine, was running low power tests when the reactor overheated leading to an explosion and radiation releasing into the atmosphere. Despite this being one of the most serious nuclear disasters in world history, causing great harm to the earth and life around it, we now know more about the dangers of nuclear energy than ever before. It is very important that we continue to strengthen our regulations to make nuclear energy a safe, reliable energy source.

Have you ever wondered why only limited countries in the world, have their hand on nuclear energy? This could have many reasons, but mainly it is due to a lack of technology, and science needed to operate such stations. Ukraine was one of such countries that opened a nuclear power plant in 1977, an era in which the majority of the developed countries turned their backs on the most popular source of energy: oil, and slowly replaced it with nuclear energy. The Chernobyl nuclear accident in the Ukraine that occurred in 1986, was caused by untrained personnel, leading to both long and short term consequences.

In the wee hours of the morning of April 26, 1986, the town was still and operation of the power plant was going smoothly. However, at 1:24 AM, 2 explosions suddenly tore through the fourth unit, sending both debris and radioactive material flying through the air (IAEA, “One Decade After Chernobyl: Summing Up The Consequences of The Accident.” 67).

Earlier in 1990 the Ukrainian parliament had voted to close the Chernobyl' plant permanently within five years, but closing the plant was repeatedly postponed because of the country's shortage of electricity. After a turbine fire in October 1991, the No. 2 reactor at Chernobyl'

The Chernobyl accident, also known as Chernobyl catastrophe is a nuclear accident that occurred on April 26th 1986 near Ukraine–Belarus border in former Soviet Union. It was the worst nuclear power plant accident in history in terms of costs and casualties. The accident happened during a systems tests and it destroyed one of four nuclear reactors. Unfortunately, due to poor plant design (no containment over the reactor) its consequences were far greater than of an atomic bomb in Hiroshima with the level of radiation being nine times larger. At the time Soviet government tried to cover that an accident ever happened, but the Swedish authirities noticed unusually high levels of radiation above Sweden. Even with a radioactive cloud spreading around the Europe, Soviet government refused to acknowledge that there was anything wrong. In the following days, winds blew 70% of radioactive particles form the place of accident to bordering Belarus and Russia contaminating south Belarus, north Ukraine and southwest Russia, even reaching all the way to the northern Europe and
